PCA data
Learn how to filter internal product development spreadsheets and verify pack sizes or medicinal forms using the British National Formulary (BNF) database.
This guide explains how to investigate #N/A errors in product development spreadsheets by cross-referencing medication pack sizes with the British National Formulary (BNF). Completing this ensures your pharmaceutical catalog data is accurate and free of calculation errors.
This applies to product development and data management teams. Use this workflow when auditing data or resolving formula errors in product control sheets.

Cross-Reference the pack size with the BNF Database





Update the Spreadsheet

Q: Why does my spreadsheet show an #N/A error in the calculation columns?
A: This typically occurs when a dependent value, such as a drug's pack size, is missing or incorrect. Verifying the correct size via the BNF website and updating the cell will resolve the formula error.
